Topic: Lawsy carriage issues

I have been having some issues with this upgrade. I bought new rods from Mcmaster-Carr and they fit very snug into the carriages. But I am having significant shimmying on the X rods. When I try to slide everything font/back to toss the belts back on, I have to firmly hold both sides of the X so it moves evenly.
I got rid of the hose clamps and threw on a few collar shafts, so the Ys aren't going anywhere. And the LM8UUs slid on easily, but do not have enough play to constitute this movement...they also seem to be properly popped into place.
Since Solidoodle's left printed Y bracket started caving in once I was loosening the belt (???), I had to replace that, so belts are not on as of yet. Could that be the issue?
Pretty bummed since I can't print till this is done sad

Re: Lawsy carriage issues

I was correct. The play was due to belts not being on. I simply jumped to worrying. I will keep this thread up just in case it may help someone in the future.

Glad it worked out.

Over-thinking/worrying is a major cause of troubleshooting in the 3D community - so you aren't alone smile

Re: Lawsy carriage issues

Ok...after fidgeting with the X belt, I got her all put together. However, when I home X, the center/front parts slams into the pulley and cannot with the switch, causing a troubling grinding sound. I have not tested a print yet due to this, but it appears to be the same case on the left Y carriage as well.

Any thoughts?

Re: Lawsy carriage issues

Aren't you supposed to add a screw that sticks out to hit the tabs? Have you got that added but not screwed in flush ? Double check the original thread and you should see what I mean.

Re: Lawsy carriage issues

Which side is it hitting?  There is no way to avoid hitting those brackets with the extruder near the front.
